Parameters

page

Image to apply radial light effect to.

center

Center point in the image (in pixels) about which the effect is applied.

amplitude

Controls the magnitude of color adjustment for each channel of the image. The number of elements of the array is typically set to the number of channels in the image. Each value should range from 0 to 2, although higher values are possible. 0 represents no change in the image color. Higher values represent more intense change. Color changes are clipped, so higher values result in a harder edge to the waveform.

frequency

Frequency of sine wave. The value should be from 0 to 0.5. The higher the frequency, the more bars will be visible.

phase

Phase of sine wave. The value should be from 0 to 2*PI (approximately 6.28). As the phase is changed, the alignment of the bars is changed. This can be used to align the bars with image content or boundaries.

attenuation

Attenuation of sine wave. The value should be from -0.01 to 0.01. Attenuation adjusts how much the amplitude of the sine wave is decreased or increased as the sine wave proceeds. It can be used to cause the lighting to fade or intensify.
